    Description: ► We propose sellers’ online interactivity strategies (SOIS) in C2C marketplaces. ► We examine impacts of each component of SOIS on consumer purchase decision making. ► We also analyze the moderating role of product type in the SOIS-perceptions link. ► Only slight image creation has a direct effect on perceived diagnosticity. ► Two components of SOIS indirectly affect perceived diagnosticity. Given that the Internet does not afford an opportunity to inspect products before purchase, some customers hesitate to shop online. Online interactivity can supplement online decision-making with added product information. Based on the theories of impression management and deception, this study focuses on sellers’ online interactivity strategies (SOIS) and aims to explore the role of SOIS played in online purchase decision-making process. According to the stimulus–organism–response (S–O–R) paradigm, this study aims to understand how each component of SOIS affects transaction intention through consumer perceptions (perceived deception and perceived diagnosticity) and how this affect is moderated by product types (search goods and experience goods) in online marketplaces. Data collected from 475 respondents support most of our hypotheses. Product type positively moderates only the link between image creation and perceived deception. Implications for theory and practice are also discussed.

    Description: Knowledge has become the key to success in the global knowledge economy, not only for organizations, but also in (VCoPs). The major challenge in sustaining a VCoP is acquiring knowledge spontaneously from members. This challenge leads to our research question: what encourages VCoP members to voluntarily and continuously help one another through continuous knowledge-sharing? In this study, we integrate three research streams—justice, trust, and (OCB)—into one model in order to analyze the antecedents of knowledge-sharing continuance intentions in VCoPs. Our model theorizes that the four dimensions of justice (i.e., distributive, procedural, interpersonal, and informational justice) affect two different referents of trust (i.e., trust in members and trust in management). We further link these trust constructs to altruism (i.e., OCB directed to the individual) or conscientiousness (i.e., OCB directed to the organization), which in turn effect the knowledge-sharing continuance intentions in VCoPs. This hypothetical model is empirically validated using data collected from 142 members of an IT-oriented VCoP in Taiwan. Our integrated model has been helpful in VCoP research as it broadens our theoretical understanding of knowledge-sharing continuance intentions.

    Description: Branded mobile applications (apps) present one of the most promising opportunities for marketers to reach current and potential customers, sell products or services, and facilitate customer engagement with brands. This study aims to explore how branded apps influence consumers’ brand repurchase intention and continuance usage intention. Integrating the utilitarian view from information systems research and the view of consumer–brand engagement from marketing research, a complementary engagement path alongside the utilitarian path was devised and tested in order to elucidate consumer perceptions toward branded apps. Independent self‐construal and interdependent self‐construal moderate relationships along the utilitarian path and engagement path, respectively. Data collected from 637 respondents support most of the proposed hypotheses. Results show that the engagement path has more influence on continuance intention and equal influence on repurchase intention when compared to the utilitarian path. Findings show that apps users have different thoughts along each of the two paths, depending on their self‐construal. The study's findings also provide app designers and marketers with new perspectives on how to better design branded apps.

    Description: AEB071 (sotrastaurin) is a specific inhibitor of protein kinase C that prevents T-cell activation. Our previous study demonstrated that AEB071 monotherapy could prevent acute cardiac allograft rejection in rats. Herein, we investigated the effects of AEB071 combined with various doses of tacrolimus (Tac) on the allograft rejection and survival in a rat heart transplantation model. Heterotopic cardiac transplantation from Brown-Norway to Lewis rats was performed. Cardiac allograft survival was assessed by monitoring heartbeats in six recipients of each experimental group. Another four recipient rats were selectively sacrificed in each group at d 7 post-transplantation for histologic examination. Serum transaminases, blood urea nitrogen, and creatinine concentrations were measured. AEB071 monotherapy prolonged allograft mean survival time (MST) compared with the untreated control group. Also a combination of AEB071 and Tac prolonged MST compared with monotherapy groups with higher dose of Tac. In the cardiac graft histology, AEB071 combined with Tac 0.6 mg/kg/d significantly decreased the rejection grade as indicative of decreased inflammatory cell infiltration into the graft. No experimental group was found with any abnormal histologic or serologic evidence of liver and kidney toxicity. AEB071 combined with a smaller dosage of Tac may be clinically possible to establish calcineurin inhibitor (CNI) minimization protocol in solid organ transplantation.

    Description: The function of type II collagen in cartilage is well documented and its importance for long bone development has been implicated. However, the involvement of type II collagen in bone marrow derived mesenchymal stem cell (BMSC) osteogenesis has not been well investigated. This study elucidated the pivotal role of type II collagen in BMSC osteogenesis and its potential application to bone healing. Type II collagen-coated surface was found to accelerate calcium deposition, and the interaction of osteogenic medium-induced BMSCs with type II collagen-coated surface was mainly mediated through integrin α2β1. Exogenous type II collagen directly activated FAK-JNK signaling and resulted in the phosphorylation of RUNX2. In a segmental defect model in rats, type II collagen-HA/TCP-implanted rats showed significant callus formation at the reunion site, and a higher SFI (sciatic function index) scoring as comparing to other groups were also observed at 7, 14, and 21 day post-surgery. Collectively, type II collagen serves as a better modulator during early osteogenic differentiation of BMSCs by facilitating RUNX2 activation through integrin α2β1-FAK-JNK signaling axis, and enhance bone defect repair through an endochondral ossification-like process. These results advance our understanding about the cartilaginous ECM-BMSC interaction, and provide perspective for bone defect repair strategies.

    Description: Mobile social networking applications (MSNAs) are readily attractive for supporting interactions and collaborations between people in a variety of mobile environments due to their low-cost and ubiquity. Departing from existing research, this study focuses on the influence of negative emotions in the context of MSNA use. Integrating theories of coping, regulatory focus, and guilt, this study proposes a research model to explore how people cope with fear (self-referenced fear and other-referenced fear) and guilt using three coping strategies (knowledge sharing, hiding, and knowledge contribution loafing) in the context of MSNAs. Also involved are two moderators (promotion-focused and prevention-focused) that exhibit different tendencies in strategy choices, thus generating a varying of behavioral results when tackling fear and guilt. Data collected from 496 members of LINE groups support most of our proposed model, which conjectures the differential effects of self-referenced fear, other-referenced fear, and guilt on coping strategies in terms of regulatory focus. Notably, this study is among the very first to explore the concerns and affects of fear and guilt in the context of using MSNAs, with rich theoretical and practical implications.

    Description: Purpose Providing that branded applications (apps) became a new trend in mobile marketing, the purpose of this study, thus, is to explore how to promote app users’ continuance intention and purchase intention (i.e. “app continuance”) toward a specific branded app. Design/methodology/approach By integrating both goods-dominant logic (GDL) and service-dominant logic (SDL), this study uses a unifying model to examine whether perceived usefulness and task-service fit (TSF) have different effects on the two parts of app continuance. This study identifies task characteristic and four service characteristics (interactivity, presence, localization and ubiquity) as antecedents of TSF. Furthermore, psychological barriers are examined as mediators of TSF and purchase intention within SDL. Data collected from 631 users of the targeted branded apps support all of the proposed hypotheses. Findings The findings show that besides perceived usefulness, TSF is an essential determinant of both app continuance in the context of branded apps and a partial mediator of psychological barriers between TSF and purchase intention. Originality/value Unlike prior studies, which have focused on traditional GDL to examine continuance intention, this study incorporates SDL and the notion of psychological barriers to explore such matters. The evidence concerning the significantly higher explanatory power of the full model suggests that a deeper understanding of the antecedents of app continuance is possible when the alternative view is taken into consideration, thus providing a promising avenue for future research.
